“气垫轴承”显神通在现代社会中,各种机器都在飞快运转着。它们的转轴上安装有各式各样的轴承,分属“滑动轴承”和“滚动轴承”两大类。传统的“滑动轴承”历史悠久,但是噪声大、磨损快,而“滚动轴承”利用滚珠、滚棒,摩擦力减少到原来的几十分之一。因此19世纪以来,基本上机 “Air bearing” brainday In modern society, all kinds of machines are running fast. They are installed on the shaft with a wide range of bearings, belonging to “sliding bearings” and “rolling bearings” two categories. The traditional “sliding bearing” has a long history, but the noise, wear fast, and “rolling bearings” using the ball, roller, friction reduced to a few one-tenth. Therefore, since the 19th century, basically machine
